Swine can be infected by bovine viral diarrhea virus (BVDV). However, transmission routes among pigs are still unknown. The objective of the present study was to induce experimental infection of BVDV-1 in weaned piglets and to assess the potential transmission through pen back pond water, used to facilit...
En la presente investigación se determinó la sensibilidad a nitrofurantoína (NTF) mediante un análisis observacional retrospectivo de informes de antibiogramas, por disco de difusión, de urocultivos provenientes de gerontes hospitalizados. En la serie observada (N=90) el desarrollo más frecuente fu...
ABSTRACT BACKGROUND: Hepatitis C virus (HCV) infection is a serious public health problem, that affects approximately 170 million people worldwide. Chronic HCV infection is associated with hepatic insulin resistance and an increased risk of diabetes HCV-infected patients has been well documented. OBJE...

Abstract Toxoplasma gondii presents a high prevalence worldwide, infecting several animals. Felines are considered the definitive hosts and among the intermediate hosts we highlight mammals and birds. The man can become infected by ingesting tissue cysts present in birds and mammals. Biological and molec...

Muitas espécies de animais silvestres de vida livre servem como reservatório de bactérias patogênicas que ameaçam a saúde humana e dos animais domésticos. Algumas bactérias, como Campylobacter jejuni, Campylobacter coli, Yersinia enterocolitica e Salmonella enterica, causam enfermidades em humano...
A retrospective study was conducted on neurological diseases of cattle in the state of Goiás, Brazil, from March 2010 to August 2017. Samples of three veterinary diagnostic laboratories were analyzed. Diagnosis was established in 170 out of 407 cattle with neurological signs. Epidemiological, clinical, ...
In recent years there has been a global increase in nontuberculous mycobacteria isolates, especially in patients with cystic fibrosis. As its clinical and radiological characteristics overlap with other infectious agents, diagnostic guidelines were generated based on evidence from patients who do not pre...
Abstract Salmonella Gallinarum is a host-restrict pathogen that causes fowl typhoid, a severe systemic disease that is one of the major concerns to the poultry industry worldwide. When infecting the bird, SG makes use of evasion mechanisms to survive and to replicate within macrophages. In this context, ...

Abstract The virulence genes in invasive aspergillosis (IA) have not been analyzed adequately. The present study was designed to evaluate the expression of gpaB and sidA genes, which are important virulence genes in Aspergillus spp. from bronchoalveolar lavage (BAL) samples. Direct examination and cultur...

The degree of antagonism exercised by fungi on geohelminth development varies according to the morphological alterations caused by different fungal species. Saprophytic fungi may exert ovicidal or ovistatic effects. The aim of this study was to apply scanning electron microscopy (SEM) to observe the acti...
